1. I have given up for now trying to upgrade my 3D printer control board.
Options are:
2. Buy a new printer [ >£200]
3. Buy a new control board [ ~£40]
4. DIY with a Raspberry Pi - which will cost an unknown amount.
It has been explored a bit here:

and here:

How to do it and what do I need.
I think a fairly up to date R-Pi, possibly a 3B+
5 Stepper motors: 1 - X-axis, 1 - Y-axis, 2 - Z-Axis, and a filament feeder
- driver hardware for these
Heating power to the filament coil and feedback thermistor.
Heating power to the Bed and feedback thermistor.
Driver hardware and A/D inputs for these.
Display and input buttons, knobs or whatever. How much of this could be done from a tablet? Or Octoprint?
Knowledge of and ability to do whatever G-codes desire.
Some of this latter stuff could be obtained from the Marlin software.
Thought - Could the Marlin software be hacked for this?
